CAP FOR RADIATORFJ Al l'l) THE LIKE.

Application filer]. May 13,

T 0 all tlJ/LOWL it may concern Be it known that l, losnrir L. 31111, acitizen of the United States, and resident of Atlanta, in the county ofFulton and State of Georgia, have invented certain new and usefulImprovements in Caps for Radiatorsand the like, of which the followingis a specification.

My invention relates to improvements in radiator caps and consists ofthe constructions, combinations and arrangen'ients herein described andclaimed.

An object of the invention is to provide an improved cap or closureadapted primarily for use in connection with the filling necks ofautomobile radiators, but also adaptable for use in connection with awide variety of styles of containers having filling openings.

Another object of the invention is to provide a cap for the fillingopening of a container which is operated by being slid to open andclosed position, there being means for so mounting the cap for slidingmovement that the cap may be particularly used either in connection withan automobile radiator or in connection with containers of differenttypes.

Another object of the invention is to provide an improved sliding capwhich is mounted for sliding movement by a very simple arrangement whichis capable of inversion to adapt the cap either for use in connectionwith automobile radiators or with containers of different types.

Other objects and advantages appear in the following specification,reference being had to the accompanying drawing, in which- Figure 1 is acentral longitudinal section of a sliding top cap adapted for use inconnection with automobile radiators or a wide variety of othercontainers having a filling opening.

Figure 2 is a side elevation of the cap alone.

Figure 3 is'a plan view of the threaded ring.

Figure 4 is an inverted plan view of the sliding top.

Figure 5 is a longitudinal section illustrating the application of theprinciples of the invention in combining the slidable cap with aradiator neck.

Figure 6 is a section taken substantially on the line 6.6 of Figure 5.

1924;. Eerial No 713,911.

Attention is first directed to Figure 1 wiich illustrates theapplication of the invention to the filling neck 1 of an automobileradiator. In the case of the filling neck 1 there is an upstandingflange 3 which is threaded at 4-. In the event that the invention isused in connection with a type of container other than a radiator, theprinciple of mounting would be the same as in Figure 1. The flange 3would then be the equivalent of the filling opening of: the container.

In order that the slidable top 5 may be applied in either of theforegoing instances, use is made of a ring 6 which is threaded at 7 sothat the ring may be screwed upon the threads 4 of the flange 3. Havingthus screwed the ring 6 into place so that the upper surface or edgecomes flush with the upper edge of the flange 3 use is made of a setscrew 8 to the ring in position. This set screw is turned from theinside, and is screwed outward until it binds against the flange 3. Thisarrangement makes it quite impossible for the ring to move in. ordinarypractice.

Formed inside of the threaded ring 6 adjacent to the upper edge is a lip9 which provides a bearing for the stud 10 by which the top 5 ispivotally mounted upon the ring.

The lip also provides a base against which one end of the spring 11presses. The other end of the spring presses against the en larged head12 of the stud. The opposite end of the stud is threaded at 13, andscrews into a lug 14.- formed inside of the slidable top 5.

The arrangement is obvious enough. The stud 10 is screwed into the lug 11 from beneath, the spring 11 being interposed between the head 12 andthe lip 9. The top and ring are thus pivotally fastened together, carebeing taken to put the spring under suflicient tension to keep the topin complete but slidable contact with the edge of the ring. A circulargroove 15 around the ring 6 receives a gasket 16 so that the joint maybe tight.

It is quite obvious from what has been said. that the slidable top capof the foregoing description is applicable not only to radiator fillingnecks but also to any type of container having a filling opening. Suchfilling openings usually have threaded por tions upon which a closurecap may be screwed. It is the purpose of the invention that the threadedring 6 shall, in such cases,

seated upon the flange 18.

take the place or" the closure cap, the threads T'heing .{s c re ivedinplace where the cap formerly was, and the top 5 taking the place of theclosure cap itself.

In Figures 5 and .6 the arrangement is somewhat different. Figure 5shows how the slidahle top may be combined with a radiator filling neck,to make a more unitary object. The filling neck 17 includes a flangelikestructure 18 as before, one side of the flange being provided with a lug19 into which the threaded end 20 of the stud 21 is screwed. The head 22of this stud bears upon a spring 23 which keeps the top 24 The stud 21,head 22 and spring 23 occupy the bore 25 in a lug 26 inside. oi the top.The flange 18 has a groove 27 in which a gasket 28 fitted to provide atight joint.

It is to be observed that the arrangement in Figure 5 is "largely a mereinversion of the arrangement illustrated in Figure 1. The mountim forthe pivot stud 21 is in the shape 0 a lug 26 carried by the top 24 inFigure 5 Whereas in Figure 1 it is the lip 9 carried hy'th e ring 6 thatprovides the mounting for the stud 10. Instead of the stud screwing intothe slid ahle top as in Figure 1 it screws into a fixed part of theradiator neck in Figure 5. The mode or operation is the same in bothinstances, but as has already been pointed out the manner of applicationor use is different. The arrangement in Figure 5 is adapted particularlyfor the radiator filling neck of the Ford automobile. The arrangement inFigure 1 can be used with almost any type of container.

'With a little modification the type of the invention shown in' Fig. 1can be adapted to radiator filling necks of automobiles other than theFord. Such modifications would consist of making the parts larger andperhaps placing the'threads 7 on the inside of the ring instead of theoutside. This particular sliding top cap may be used on oil crankcases'of automobiles trucks, etc.

operation, it is merely necessary to push either the top 5 or 24: to oneside upon its pivot in order to gain access to the filling opening. Itis a matter of quite common experience for those driving automobiles tospend no little time in both unscrewing and rescrewing the cap of theradiator when filling the radiator with Water. It sometimes happens thatthe threads will not start righ; and it invariably happens that the capis not roperl v centered upon the filling neck thus presenting anunsightly appearance. By the use of the style of sliding cap hereindisclosed these objections are eliminated and in the event that theslidahle top is supple-- mented with an ornamental figure. as is oftenthe custom, there will never be any likelihood oi" such figure beingplaced one sided upon the radiator.

\Vhile the construction and arrangement of the improved radiator cap asherein dcscribed and claimed is that of a generally. preferred form.obviously mmlifications and changes may be made Without departing fromthe spirit of the invention or the scope of the claims.

I claim:

1. A device of the character described comprising a top having a lugwith a threaded opening. a threaded ring arranged to be screwed upon thethreaded portion of a radiator filling neck, means including a set screwcarried by the ring for fixing the ring in position, a lip carried bythe ring, a stud providing the pivotal connection for the top upon thering so that the top may be swung: across the filling neck at rightangles to the axis of the opening, said stud having a threaded end toenter said threaded opening and having a head, and means including aspring situated on the stud between the head and said lip to seat thetop under tension.

2. A device of the character described comprising a top, a separablering having an internal lip, a pendant stud in'm'iovably fixed upon thetop and passing through the lip, and a spring mounted on the stud toexert pressure between the stud and loop to keep the top seated upon thering.

A. device of the character described comprising a top having a lugformed thereon, a separable ring insertuble n the filling opening of acontainer. said ring having a circular groove and a. lip. gasket in thegroove, a stud fixed in the lug and oxtending through the lip, and aspring mounted on the stud pressing against the lip to seat the top uponthe gasket.
